Given a string str. The task is to check whether this string can be splitted into two strings X and Y such that Y is a substring of X X + Y = str (Here, X+Y means X and Y are concatenated) Examples : Input: pleaselea Output: Yes str = “please” + “lea”, Here “lea” is a substring… Read More »
Given a Binary String S of length N which consists of only 0 and 1, the task is to remove minimum number of 0’s from the string such that all 1’s form a contiguous subsegment. Return numbers of 0’s which are removed, if the string is already having all 1’s in contiguous format return -1. Examples: Input :… Read More »
Given a string S containing 0’s and 1’s, the task is to find the length of longest continuous substring of 0’s from the given string. Examples: Input: S = 1111111 Output: 0 Explanation: There is no substring of 0’s hence output is 0. Approach: The given problem can be solved by simply iterating through the string. Follow the… Read More »
Given n strings in any order. Sort all the strings (lexicographically), but if a string is present completely as a prefix in another string, then string with larger length should come first. Examples: Input : 3 cap apple captain Output : apple captain cap Explanation: cap is present in captain as a prefix, so string : captain being… Read More »
The string.h header defines one variable type, one macro, and various functions for manipulating arrays of characters. Functions provided by string.h The string.h header file declares a set of functions to work strings. To perform operations like comparison, concatenation, and copying, this string.h library is widely used. This header file defines several functions to manipulate C strings and… Read More »
In this article, you’ll learn about strings in C programming. Strings are defined as an array of characters. The difference between a character array and a string is the string is terminated with a special character ‘\0’. Example : char name[] = “first name” ; Declaration of strings : When the compiler encounters a sequence of characters enclosed… Read More »
